"Application February 'It 1945,1Serial No. 576,580

l 'I'his invention relates wells and it is an object of the invention toprovide a'device of this kind which may be -employed to advantage inremoving bearingsand junk.

It is also an object of the invention .to provide a device of this kindconstructed in a manneri to 1 claim, (ci. zalssi to ailshing tool forLdeep 2 is' ,suitably formed, gs at 8,' for coupling with a conventionaldrin n o provide an upper basket to hold bearings and junk of relativelysmall sizes, together with a lower or bottom basketl for catching conesor other relatively large articles.

The invention consists in the details of con-v struction and in thecombination and arrangement of the'several parts of my improved ilshingtool for deep lwells whereby certain importantv advantages are attained,as will bef hereinafter more fully'set forth.

In order that my invention may be the better understood, I will nowproceed to describe the vsame with reference to the accompanying draw-Figure 1 is a longitudinal sectional view taken lthrough a toolconstructed in accordance with an embodiment of the invention;

Figure 2 is la sectional view taken substantially on the line 2-2 ofFigure 1; and

Figure 3 is a sectional view taken substantially on the line 3 3 ofFigure 1.

Figure 4 is an enlarged lfragmentary view taken substantially on theline I-I of Figure 3.

As disclosed in the accompanying drawings,

mediately below and adjacent to the coupling means :8. is enlarged to`provide a surrounding head and immediately below this head the stem Ihas extending outwardly therefrom the equidistantly andcircumferentially spaced wings or lugs I Il, the outer edges a of whichare outwardly anddownwardly inclined, whereby the wings or lugs IIIprovide effective meansto prevent the tool from hanging on pipes orledges Iwhich would otherwise'interfere with the desired removal of thetool. .4 f

The outer lower portion of the wings or lugs III are downwardlydisposed, as at Il, to provide depending fingers with which are engagedfrom below the upper portion of a sleeve I2 which surrounds the innerportion of the stem 4 and is interposed between the outer portions ofthe wings or lugs I Il and a shoulder I4 provided at'the upperpart ofthe body member B. The sleeve I2 is held in place by welding, as at I5,or otherwise as may be preferred. Y

'I'he portion I6 of the body member B above the shoulder I4 is slightlyreduced and with which maintained effectively in applied position.

the fishing tool comprises a cylindrical member B oi desired dimensionsand which is provided with a downwardly facingand relatively deep pocketor basket I open at the bottom of the body member B and which pocket orbasket I is adapted to receive cones or other relatively large objectsAs is clearly illustrated in the accompanying drawings, the sleeve' I2is spaced from the stem 4 whereby is provided a basket Il open at itstop and towhich access is had in the spaces between adjacent wings orlugs I0. It is also to be noted within a deep well and be retainedtherein by the catches 2 whereby such cones or the like can be readilyrecovered. I

The bottom edgev of the body member B detlning the open end of thepocket or basket I 4The upper end of the body member B at its axialcenter is continued by a relatively long tubular stem 4 in communicationwith the pocket or basket I at the top thereof through the port 5.

j The upper portion of this port 5 is formed to provide 'a surroundingseat 6 upon which is adapted to be seated, upon being dropped into thestem 4, a valve member 'I herein disclosed as requisite dimensions andweight.

The upper or outer end portion of the stem l a ball of that the innerface f theapplied sleeve I2 is outwardly of the perip ery of the head 9whereby is facilitated collection between the basket I 1 oi thebearings, junk and btherl relatively small bodies. l I

In communicatioii, Aas at I 8, with the bore I9 of the stem 4 at desiredpoints above the valve seat 8 are the inner ends of the circulatingpassageways or water courses 20( which arel extended through the bodymember B outwardly of the 4pocket or basket I and opening through thebottom edge face of the body member B. These passageways or eourses220are preferably four in number and equidistantlyspaced around the bodymember B` although the number and location may be varied if desired.

The valve member 'I controls the flow or circulation-of the Waterthrough the tool. After the bearings, junk and kindred matter have been'collected in the upper basket Il, the valve mem- 'ber 'I is droppedthrough the tool to engage its The upper portion 9 of the stem 4 and"imseat 6 which closes flow through the port 5 and causes the flow to bethrough the passageways or courses 20. With the now closed through theport 5, the bucket or basket I can then 'be employed to advantage topick up cones or the like which may be within the well.

What is claimed is:

A ilshing tool for deep wells, comprising a relatively long body havinga. pocket formed in and opening through one end oi the body, the said-one end constituting the lower end of the tool when in use, said pocketproviding means for receiving' a body from the bottom of a weil,retaining catches carried by the lower portion of the body within thepocket and extending radially toward the center thereof, a reduced stemextending upwardly from the top of the pocketed body upon the axialcenter thereof and formed at its free end to provide a coupling meansfor connecting the tool in'a well pipe line, a 20 2,090,616

sleeve mounted upon the upper end of the body and ypartially surroundingthe stem. said sleeve being open at its top and spaced from the stem tovprovide a material receiving basket, the stem above the sleeve beingprovided with outstanding wings having their outer edges downwardly andoutwardly directed, the upper end portion of the sleeve being directlyengaged with the lower edges of the wings, the outer portions of thewings having parts overlying the upper portions of the sleeve, the lowerend portion of the sl'eeve being permanently joined with the upperportion of the body.
